Application April 14, 1944, Serial No. 531,111

The present invention relates to continuous strip wiping apparatus embodying wiping members between which the strip is movable. The object of the invention is to provide improvements in means for eliminating any non-wiping interval between the engagement of the strip by one pair of wiping members and the next succeeding pair, it being understood that when the wiping pads on one pair of wiping members are worn out another pair of wiping members with new wiping pads must be brought into wiping position.

For a consideration of what I believeto be novel and my invention, attention is directed to the following specification and the claims appended thereto. a

In the drawings forming part of this specification-- Fig. 1 is a plan view. of the improved wiping apparatus disposed above a hot coating pot.

Fig. 8 is a cross section of Fig. 7.

Fig. 9 is a fragmentary sectional view on line 9-9 of Fig. 3.

The improved apparatus comprises a suitable frame ill adapted for seating on a galvanizing pot ii. The strip to be wiped is indicated at i2 and moves upwardly from beneath the usual holddown roll i 3 in the pot.

The strip wiping members consist of a series of pairs of members it and it carried by horizontally-disposed radially-spaced axles l6 and.

i l. The axles are adapted to be turned in unison in opposite directions by means presently de- 25 each rod is threaded to .receive a nut 28 to form an abutment for the right-hand side of the journal block l9. It will therefore be seen that the journal block l9 and the cross head 26 are interconnected by means of the upper and lower rods 28 and 2|.

Extending upwardly from the base frame in and between the pedestals'22 and 23 is a spring abutment 29. Near its lower end this abutment is apertured to permit free passage of the lower rod or, rods 2l. Positioned between the journal block it and the abutment is a. compression spring 39 and positioned between the crosshead 26 and the abutment is another similar spring 31. The blocks l8 and i9 are, therefore, yieldingly pushed towards each other as will now be readily understood. At times it is necessary to compress the springs for a purpose hereinafter appearing.

scribed to bring the paired wiping member into strip wiping position, one after the other as the Wiping pads on the leading pair become worn.

The said axles are supported at their ends in journal boxes or blocks of which those for the axle it are indicated at I8 and those for the axle ii at H). These journal blocks are each slidably supported on upper and lower guide rods 20 and 2i which are themselves slidably supported by a series of pedestals 22, 23, 26 and 25 secured to the base frame it. The left-hand ends of each set of upper and lower rods extend through a crosshead 2t removably secured on the rods by nuts 2?, inwardly irorn the right-hand pedestals The means for compressing the springs comprises a shaft 32 for each pair of springs. Each shaft is .journaled in a bearing in the spring abutment 29 and is held against axial movement by a pair of collars 33 amxed to the shaft at opposite sides of the abutment. extended throughthe crosshead 26 to receive a spoked hand wheel 36 for turning the shaft. The spring 30 instead of bearing directly against the journal block l8 bears against a plate 35 having a hollow spring-centering lug 36 wherein there is mounted a nut 3ithrough which the shaft 32 extends so that as the shaft is turned to move the nut towards the left the spring 39 will be compressed by reason of theplate being forced towards the left by the nut. Likewise, the spring 3| instead of bearing directly against the crosshead 28 bears against a plate 38 similar to the plate 35 and like the latter having a hollow spring-centering lug and a nut therein through which the shaft extends so that as the shaft 32 is turned to compress the spring so the spring 3! will also be compressed as will now be readily understood. The nuts 31 have some free axial movement in the hollow lugs 36 on a spline (it so that they may be backed away from abutting engagement with the ends of said lugs as will be readily understood. The two shafts 32 are interconnected for joint rotation by a sprocket 39 on each shaft and a connecting chain 40.

The means for turning the axles I8 and I! for changing the wiping members comprises a shaft ii iournaled in a bearing t2 and held against axial movement therein by a pair of collars it amxed to the shaft at opposite sides of the hearing. The shaft also extends through alined apextures in two pairs of spaced arms at and it and This shaft is I stood.

' the same passing shown by the arrows.

is turned by a hand wheel 48. Splined on the shaft between each pair of arms 44 and 45 are two worms 48 and 41. The arms 44 extend from the journal block it and the the Journal block IS. The worms engage worm wheels on the outer ends of the axles I6 and H, the worm wheel for the axle l6 being indicated at 48 in Fig. 6. The threads of the two worms run in opposite directions and, therefore, when the shaft isturned the axles will be turned in opposite directions as will now be readily under- Each of the wiping members l4 and I5 consists of a bar 50 substantially longer than the width of the strip l2 to be wiped and carries on its front face a removable wiping or the like. A plurality bars are hingedly secured to the axle l6 and a similar number is secured to the other axle i1, it being understood that the bars extend parallel with the'axles. It may be here stated that this hinging of the wiping bars to the axles is one of the important features of the invention for reasons that will become apparent as the description proceeds. The hinge pins are indicated at 5|, through a pair of hinge ears on the bar and a hinge ear 53 therebetween, the hinge ears 53 constituting the points of star wheels 54 ailixed to the axles. It will thus be seen that, by means of these hinge pins, the wiping bars are individually pivotally supported on the axles at points spaced radially from the axes thereof.

As the wiping members on one axle come into opposition with the wiping members on the other axle, it is a feature of the invention'that they are held in opposed alinement as they approach wiping position and during such position. The preferred means for thus holding said members in opposed alined position comprises pins and sockets 55 and 56 carried by said bars, this arrangement permitting relative sliding movement between the members while alinement. The pins and sockets are at the extreme ends of the bars, the preferred arrangement being a pin at one 1nd of the bar and a socket at the other end.

In Fig. 3 the strip is being wiped by the members of the pair A and the wiping members of a second pair B are in opposed relation ready for intercoupling on turning of the axles in the direction Turning of the axles eventually causes the pair 13 to come into wiping contact with the strip while thepreceding pair A is still in wiping contact with the strip as shown in Fig. 4. It will be understood that the squeezing force applied by the springs 30 and 3i to the leading pair A is gradually transferred to the pair B by the rotation of the two axles. On continued turning movement of the axles the leading pair A becomes uncoupled and because the members thereof are hinged they will swing downwardly by gravity free and clear of the strip as indicated by the pair C. When the wiping members of pair B are in the position shown in Figs. 3 or 4, the bars 50 of the next succeeding pair D are accessible for replacement of their pads either by substituting a reserve set of bars or by leaving the bars in place and installing new pads on the bars. The members of the pair D are then swung by hand towards each other so as to be ready for arms 45 extend from" I pad 49 of asbestos (six are shown) of these retaining horizontal derstood.

automatic intercoupling like the pair B in Fig. 3 as the axles are turned as will now be readily un- From the foregoing it will be seen that by hingedly supporting the pad carrying bars 50 on axles it is made possible for the pair of wiping members next following the pair that is already in wiping contact with the strip to be advanced into wiping contact with the already wiped strip behind the leading pair of wiping members before the leading pair is disengaged from wiping contact with the strip, thus insuring that changing of the wiping member will not result in an unwiped portion of the strip as is usually the case with conventional wiping apparatus.

What I claim asnew 'and desire to secure by Letters Patent is:

1. In apparatus for wiping moving strip, the combination which comprises a pair of rotatably mounted supports, means for coordinate rotation of said supports, a series of wiping members disposed about each support and hingedly connected thereto, and means comprising cooperating pins and sockets carried by said members for interconnecting opposed wiping members in facing position for movement into wiping contact with the strip advancing therebetween.

2. In apparatus for wiping moving strip, the combination which comprises a pair of rotatably mounted supports, means for coordinate rotation of said supports, a series of wiping members disposed about each support andhingedly connected thereto, and means for holding opposed wiping members in facing position for movement into wiping contact with the strip advancing therebetween,the circumferential spacing between the members about each rotatable support being suffi- -ciently close to permit the pair of wiping members next following the pair already in wiping contact with the strip to be moved into like wiping contact before the leading pair has been moved out of such contact.
